平面的导航条看多了，想不想做个3D的，当然制作的方法很多，真是仁者见仁，智者见智。我试着做了个按钮式的，效果还不错，每一个菜单项看起来都是一个个的按钮，制作方法也不复杂，并且大小只有几k，算瘦小的了。你只要有点html和CSS的基础知识就够了。
下面我们开始制作：
第一步：
用Dreamweaver建立一个3x1的表格，宽度为70px，不设高度值，边框设为0，间距（cellspacing）为2。
第二步：
在上面已经建立好的表格的单元格中分别插入一个1x1的表格，高度值和宽度值均设为100%，边框和间距都设为0，并在每个表格中填上菜单名称。
代码是：
<table width="70" border="0" cellpadding="0" cellspacing="2">
<tr>
<td>
<table width="100%" border="0" cellpadding="0" cellspacing="0" height="100%">
<tr>
<td >互动学校</td>
</tr>
</table>
</td>
</tr>
<tr>
<td>
<table width="100%" border="0" cellpadding="0" cellspacing="0" height="100%">
<tr>
<td>市场专家</td>
</tr>
</table>
</td>
</tr>
<tr>
<td>
<table width="100%" border="0" cellpadding="0" cellspacing="0" height="100%">
<tr>
<td>资讯中心</td>
</tr>
</table>
第三步：
现在我们建立两个CSS样式分别取名为up和down，代码如下：
.up{
border:3 outset royalblue;color:yellow;font:12px;text-align:center;background:blue;cursor:hand
}
说明：边界为3，采用outset即突起样式，颜色为royalblue，字体颜色为黄色，字体大小为12px，居中对齐，背景颜色为blue，鼠标式样为手型。
.down{
border:3 inset royalblue;color:#33ff33;font:12px;text-align:center;background:blue;cursor:hand;position: relative; left: 1px; top: 1px
}
说明：边界样式为inset即内凹，字体颜色为#33ff33，position: relative; left: 1px; top: 1px可以产生1个像素的位移，这样按钮按下去时效果好些。
第四步：
对第二步所做的表格添加样式和行为，即在table标签后加上下列代码：
class=up onMouseDown="className='down'" onMouseUp="className='up'" onMouseOut="className='up'" onclick=window.open("http://www.ccidnet.com/school/web","_blank")
说明：在通常以及鼠标弹起和移出时采用up样式，在鼠标按下时采用down样式，链接采用onclick，不要用a，因为后者在访问后会留下难看的虚线框。
另外，你还可以再加点修饰，如CSS滤镜等，不过切忌太花哨，否则反而效果不好！
为了方便你学习，下面提供了全部的代码，你可以把它们复制到写字板，生成一个txt文件，然后把文件扩展名该成htm，就可以用IE直接打开了！
